Lumin with S booster PSU ? ??

anyone here have tried Lumin T2, D2 or U1 Mini w/ the S-booster PSU ?

Yup, D2 swap.

In short - bigger sense of energy and urgency, more precision, better handling of poorly recorded music (presumably because there is a reduction in digital hash/noise), better separation (or more defined separation).

Its very easy to do the swap and make it reversible, just don’t follow the Sbooster instructions regarding ‘cutting’ a wire.

So it is possible to install the kit without cutting the wire? How do you remove the IEC inlet in that case, if not cutting the cord to the power switch?

I have a D2/Sbooster and second Mikey’s impressions. There was a slight but present glare that disappeared with the Sbooster. Much prefer the Sbooster. I did cut the wire.

I just tried the Sbooster with my T2… i did not notice a noticeable difference in sound quality of any kind.

As most audiophiles… I was looking for something magical to happen. But i didn’t.

So it will get returned.


Yes it is possible. Simply unsolder it.

Yes U1 mini S-booster swap (without cutting the wire).
I find the U1 with greater dynamic range, softer / more musical, better separation of voices / instruments.

I use my D2 with an Sbooster. My impressions mirror those of Mikey. It really removed a digital glare I noticed with the stock D2, and as an upgrade it was well built. I liked the stock D2 but had some concerns until I upgraded to the Sbooster. Now, I’m quite happy many months on.
